A cut-through forwarding-enabled device forwards a frame after it receives the first 64 bytes of the frame. This feature reduces the transmission time of a frame and enhances forwarding performance.
With cut-through forwarding, the device forwards CRC-error frames because it starts forwarding frames before their CRC field is received.
This feature is not available on the two SFP ports on the back panel of an S6850-56HF or S9850-4C switch.
1. Enter system view.
2. Enable cut-through forwarding.
By default, cut-through forwarding is disabled.
